Overview

• The order temporarily bars the administration from federalizing Illinois Guard units or using Guard troops in the state for the next two weeks, according to the court filing.
• Before the ruling, about 500 Guard members had been positioned in the region—200 from Texas and 300 from Illinois—with some seen patrolling an ICE facility in Broadview under an initially planned 60‑day posture, officials and media reported.
• Illinois and the City of Chicago filed suit to block the deployment as unlawful, while the government argued the troops were needed to protect ICE personnel and federal property from threatened and actual violence.
• Courts have checked similar efforts elsewhere, including repeated injunctions against Guard stationing in Portland reported earlier this week.
• The administration’s legal rationale drew added attention after adviser Stephen Miller invoked “plenary authority” under Title 10 during a CNN interview that briefly cut out in what the network called a technical problem.
